There are many criticisms leveled at Walmart, one of the world’s largest retailers. However, Walmart is fast becoming a leader in corporate sustainability. The retailer’s latest announcement is one good example. Walmart recently announced that it will buy LED ceiling lighting fixtures for new supercenters in the U.S., stores in Asia and Latin America, and Asda locations in the U.K. This is the company’s largest purchase of LED lighting.
LED fixtures will use 40 percent less energy and help the company reach its goal to reduce the kilowatt hours (kWh) per square foot of energy required to power its buildings by 20 percent globally by 2020. The installation of the LED ceiling fixtures will begin at Asda, Walmart’s stores in the U.K. A total of 200 new Walmart stores will install the LED fixtures over the next two years.
Sales floor lighting accounts for about 90 percent of the total lighting usage in each building. Switching to LED fixtures will reduce energy use by more than 5 percent per store in the U.S. alone and will save an expected 340,000 kWh per store. That equals $34,000 in savings per year in each store -- or removing 327,360 metric tons of carbon emissions from the atmosphere. The LED fixtures are expected to save a total of 620 million kWh over the next 10 years.
Walmart projects that the LED fixtures will result in 15 percent energy savings in 30 new U.S. stores. The expected savings for other regions include:
“We have worked to find and scale energy-efficient LED lighting solutions that are cost effective and high quality, and now working with GE, we’re paving the way to make this a mainstream solution for the retail industry,” said Doug McMillon, president and CEO of Walmart.
